Balancing Procedure

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2003 GMC Savana Special, 2003 GMC Savana Camper Special, 2003 GMC Savana, 2003 Chevrolet RV Cutaway, and 2003 Chevrolet Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

Important  : The refrigerant oil in the A/C system must be balanced during compressor replacement.

  1. The replacement compressor is shipped with the total system capacity of refrigerant oil.
  2. Before installing the compressor, the refrigerant oil will have to be partially drained:
    1. Refer to the amount of refrigerant oil recorded during the compressor removal.
    2. Subtract the amount recorded from the total system capacity. Refer to Refrigerant System Capacities .

      The difference between the total system capacity and the recorded amount is the calculated amount to be drained from the replacement compressor.

  3. Drain the calculated amount of refrigerant oil from the replacement compressor.
